WAS HER FOR PAPER-PULP AND OTHER FIBROUS MATERIAL.

SPECIFICATION formingpart of Letters Patent No. 258,209, dated. May 23, 1882.

Application filed January 25,1882. (No model.)

To all whom it may concern:

Be it known that we, CHRISTIAN ANDERSON and THOMAS PATTEN, citizens of the United States, residing at Neenah, in the county of Winnebago and State of Wisconsin, have invented anew and useful Improvementin Washors for Paper-Pulp and other Fibrous Material, of which the following is a specification.

Our invention relates to improvements in washers for paper-pulp and other material of a fibrous nature, in which a receiver is suspended inside the washer or revolving drum,

which gathers the impure water of the pulp in such a manner that it does not revolve therewith, but retains its position independent of its revolutions, and discharges its contents freely through the openings in the flanged cylinder attached to the end of the washer.

It consists, also, of the method of constructing the suspending-lugs of the receiver, whereby they can be renewed easily and quickly when worn.

It still further consists of the improved form given to the flanged cylinder through which the water is discharged outsideof the washer.

The objects of our improvements are, first, to enable the paper-manufacturer to wash a greater amount of material in a given time and to perform the work in a superior manner; second, to simplify the construction of the washers and lessen their cost. We attain these objects of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal vertical section of the washer supported in the vat containing the material to be operated upon, a part of the vat only being represented. Fig. 2 represents a transverse section on the line a a of Fig. 1.

Figs. 3 andetrepresent end views of the receiver:

from entering, but allowing the impure water to pass the meshes of the cloth and be gathered up by the buckets E as they are revolved in the direction of the arrow. As the vbuckets in the revolution of the washer reach the position of E they commence to discharge their contents into the receiver It. The receiver R is closed at the end b b, and being open at the end b b, its form, as represented, causes the Water as it is received from the buckets E to flow toward b b and out through the opening D. At the outer end of receiver R are arms and at the inner end the detachable lug 1. Upon the inner end of the gudgeons O and G are formed recesses, which receive the lugs r and r and support the receiver R in the revolutions of the washer. These lugs r and r are made detachable from the receiver R for the purpose of forming them of some non-corrosive metal unaffected by the chemicals entering into the manufacture engaged in, and also to easily and quickly replace them when worn. Their hearings in the gudgeons G and G can also be lined with a non-corrosive metal best adapted to the purpose.

The receiver R is represented as of semi circular and semi-elliptical form at its extremities, but may be formed as a section of a cone, thereby giving the water-passage the requisite inclination, the buckets E being of the required shape to direct the water gathered in The gudgeon O has two or more arms extending from its hub to the flanged cylinder 0. From the hub of gudgeous G and O respectively extend shafts g and c, to receive the requisite gearing and support the washer in its appropriate bearings, thereby dispensing with the shaft through the washer. Upon the inside of the flanged cylinder 0 is an extension internal flange, G which is bored the proper size to receive the end b of the receiver, whereby a close joint is formed, preventing the water as it is discharged from the receiver from re-entering the washer, and by its declination causing an impetus toward the open end,where it discharges into its appropriate receptacle.

We are aware that previous to our invention their revolutions into the aforesaid receiver.

f f, in which is secured the detachable lug r,

thereof, and upon its extremity is formed the a receiver suspended in the central portion of the washer has been used, said receiver suspended from the central shaft, also from stationary shafts extending through the tubular journals, both of which methods we dispense 5 with, and simplify the construction, as above described.

What we claim, and desire to secure by Letters Patent, is

1. In a washer for paper-pulp, the suspenro sion of the receiver R by lugs 1' and r from the gudgeons G and G, so,that it will remain at rest independent of the revolutions of the washer A, substantially as described.

2. In a receiver suspended as abox e de- 1 5 scribed, the detachable lugs r and 4", substan- CHRISTIAN ANDERSON. THOMAS PATTEN.
